プローブ。[Claim for Utility Model Registration] A Hall element is installed in the magnetic field of a magnet, and a change in the Hall electromotive force generated in the Hall element due to the presence of a carburized part inside the specimen is used as a detection signal to detect the carburized part inside the specimen. In a carburization detection probe that detects, a first magnet and a second magnet are arranged in directions perpendicular to each other, and between the magnetic poles of the first magnet,
A first Hall element is provided in a direction substantially parallel to or perpendicular to the lines of magnetic force, and a second Hall element is provided in a direction substantially parallel to or perpendicular to the lines of magnetic force between the magnetic poles of the second magnet. Carburization detection probe.
